RE: your request: note that most people just add an empty to the scene and use that as the target object for focus. You can then position the empty wherever you'd like, at the front of another object if you'd like

Good point, two possibilities:1) The scene scale is way, way off.or2) The fstop he's choosing is very high, and he's choosing other high-numbered apertures to compare against. It's going to be completely unobvious of any difference between f/16 and f/22 in a normal indoors scene, depending on scale and focal point.

zukazuka, can you show or tell us what you were setting specificially ?

Hi, I'm experimenting with more wide angle aperture settings like F2.8 and smaller number (wider aperture).

I created a simple model with 3 cubes about 2 units which I'm guessing is always equal to meters - (standard new blender object), camera about 5.56 units away from first cube (cubes spaced further and further away for distance) - YES I do notice depth of field now... But I've got it set down to like F0.5 and I was expecting the depth of field to be so thin that only a little is in focus.

Just for reference I have a 50mm F1.2L canon lens for my camera - at F1.2 the depth of field is so razor thin you have to be really really accurate with your focus. I'm finding that if I set lens radius to about 0.3 it gets the type of results I'm trying to achieve. So yes it is working, and yes I guess you could say I'm working at the more extreme ends of the scale... Even at F2.8 I would expect the depth of field to be a lot thinner than it actually is...

I tried creating an empty and setting the that object as the focus target. This is working good, but in a few cases maybe the camera angle or something is making it not seem to focus where I want. If the empty is in the corner of the camera image would this distort it? does the empty have to be relatively near the center of the camera field of view or are there any other limitations that you can think of?

This is some cool stuff man! I can't believe I haven't tried DOF earlier... redoing all my models now with some DOF hehe...
